or source capability. Thus they generate little or no noise of

their own while providing a low resistance path for an external

driver. These devices connect input and output ports through

an n-channel FET. When ther gate-to-source junction of this

FET is adequately forward-biased the device conducts and

the resistance between input and output ports is small. With-

out adequate bias on the gate-to-source junction of the FET,

has hot insertion capability.

The low on-resistance and simplicity of the connection

between input and output ports reduces the delay in this path

to close to zero.

The FST163213 provides four 12-bit TTL-compatible ports

bus exchange and switch enable functions.

DESCRIPTION:

The FST163213 belongs to IDT's family of Bus switches.

Bus switch devices perform the function of connecting or

isolating two ports without providing any inherent current sink
